Tymlos

1 INDICATIONS AND USAGE TYMLOS is a human parathyroid hormone related peptide [PTHrP(1-34)] analog indicated for the: Treatment of postmenopausal women with osteoporosis at high risk for fracture or patients who have failed or are intolerant to other available osteoporosis therapy. Treatment to increase bone density in men with osteoporosis at high risk for fracture or patients who have failed or are intolerant to other available osteoporosis therapy.

1.1Treatment of Postmenopausal Women with Osteoporosis at High

Risk for Fracture TYMLOS is indicated for the treatment of postmenopausal women with osteoporosis at high risk for fracture (defined as a history of osteoporotic fracture or multiple risk factors for fracture), or patients who have failed or are intolerant to other available osteoporosis therapy. In postmenopausal women with osteoporosis, TYMLOS reduces the risk of vertebral fractures and nonvertebral fractures.

1.2Treatment to Increase Bone Density in Men

with Osteoporosis at High Risk for Fracture TYMLOS is indicated to increase bone density in men with osteoporosis at high risk for fracture (defined as a history of osteoporotic fracture or multiple risk factors for fracture), or patients who have failed or are intolerant to other available osteoporosis therapy.

Recommended dosage is 80 mcg subcutaneously once daily; patients should receive supplemental calcium and vitamin D if dietary intake is inadequate. Administer as a subcutaneous injection into periumbilical region of abdomen. Administer initially where the patient can sit or lie down in case symptoms of orthostatic hypotension occur. ( 2.2 , 5.2 )

2.1Recommended Dosage The

recommended dosage of TYMLOS is 80 mcg administered subcutaneously once daily. Patients should receive supplemental calcium and vitamin D if dietary intake is inadequate.

2.2Administration Instructions Administer

TYMLOS as a subcutaneous injection into the periumbilical region of the abdomen. Rotate the site of the injection every day and administer at approximately the same time every day. Do not administer intravenously or intramuscularly. Administer the first several doses where the patient can sit or lie down if necessary, in case symptoms of orthostatic hypotension occur . Visually inspect TYMLOS for particulate matter and discoloration prior to administration.

TYMLOS is a clear and colorless solution. Do not use if solid particles appear or if the solution is cloudy or colored. Provide appropriate training and instruction to patients and caregivers on the proper use of the TYMLOS pen.

2.3Treatment Duration The

safety and efficacy of TYMLOS have not been evaluated beyond 2 years of treatment. Use of the drug for more than 2 years during a patient's lifetime is not recommended.

Osteosarcoma: Avoid use in patients with increased risk of osteosarcoma including patients with open epiphyses, metabolic bone diseases including Paget's disease, bone metastases or history of skeletal malignancies, prior external beam or implant radiation therapy involving the skeleton, and hereditary disorders predisposing to osteosarcoma. Orthostatic Hypotension: Instruct patients to sit or lie down if symptoms develop after dose administration. Hypercalcemia: Avoid use in patients with pre-existing hypercalcemia and those known to have an underlying hypercalcemic disorder, such as primary hyperparathyroidism. Hypercalciuria and Urolithiasis: Monitor urine calcium if pre-existing hypercalciuria or active urolithiasis are suspected.

5.1Risk of Osteosarcoma Abaloparatide

caused a dose-dependent increase in the incidence of osteosarcoma in male and female rats after subcutaneous administration at exposures 4 to 28 times the human exposure at the clinical dose of 80 mcg . It is unknown whether TYMLOS will cause osteosarcoma in humans. Osteosarcoma has been reported in patients treated with a PTH-analog in the post marketing setting; however, an increased risk of osteosarcoma has not been observed in observational studies in humans. There are limited data assessing the risk of osteosarcoma beyond 2 years of TYMLOS and/or use of a PTH-analog . Avoid TYMLOS use in patients with (these patients are at increased baseline risk of osteosarcoma): Open epiphyses (pediatric and young adult patients) (TYMLOS is not approved in pediatric patients) . Metabolic bone diseases other than osteoporosis, including Paget's disease of the bone.

Bone metastases or a history of skeletal malignancies. Prior external beam or implant radiation therapy involving the skeleton. Hereditary disorders predisposing to osteosarcoma.

5.2Orthostatic Hypotension Orthostatic

hypotension may occur with TYMLOS, typically within 4 hours of injection. Associated symptoms may include dizziness, palpitations, tachycardia, or nausea, and may resolve by having the patient lie down. For the first several doses, TYMLOS should be administered where the patient can sit or lie down if necessary .

5.3Hypercalcemia

TYMLOS may cause hypercalcemia. TYMLOS is not recommended in patients with pre-existing hypercalcemia or in patients who have an underlying hypercalcemic disorder, such as primary hyperparathyroidism, because of the possibility of exacerbating hypercalcemia .

5.4Hypercalciuria and Urolithiasis

TYMLOS may cause hypercalciuria. It is unknown whether TYMLOS may exacerbate urolithiasis in patients with active or a history of urolithiasis. If active urolithiasis or pre-existing hypercalciuria is suspected, measurement of urinary calcium excretion should be considered .

4 CONTRAINDICATIONS TYMLOS is contraindicated in patients with a history of systemic hypersensitivity to abaloparatide or to any component of the product formulation. Reactions have included anaphylaxis, dyspnea, and urticaria . Known hypersensitivity to TYMLOS.

8.1Pregnancy Risk Summary

TYMLOS is not indicated for use in females of reproductive potential. There are no human data with TYMLOS use in pregnant women to inform any drug associated risks. Animal reproduction studies with abaloparatide have not been conducted.

6.1Clinical Trials Experience Because

clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Adverse Reactions from Clinical Trial in Postmenopausal Women with Osteoporosis The safety of TYMLOS was evaluated in a randomized, multicenter, double-blind, placebo-controlled clinical trial in postmenopausal women with osteoporosis aged 49 to 86 years (mean age 69 years) who were randomized to receive 80 mcg of TYMLOS (N = 824) or placebo (N = 821), given subcutaneously once daily for 18 months . In this study, the incidence of all-cause mortality was 0.4% in the TYMLOS group and 0.6% in the placebo group. The incidence of serious adverse events was 10% in the TYMLOS group and 11% in the placebo group.

The percentage of patients who discontinued study drug due to adverse events was 10% in the TYMLOS group and 6% in the placebo group. The most common adverse reactions leading to study drug discontinuation in the TYMLOS group were nausea (2%), dizziness (1%), headache (1%), and palpitations (1%). Table 1 shows the most common adverse reactions in the trial.

These adverse reactions were generally not present at baseline, occurred more commonly with TYMLOS than with placebo, and occurred in at least 2% of the patients treated with TYMLOS.

At later time points the incidence was generally similar between the treatment groups. Adverse reactions of orthostatic hypotension were reported in 1% of patients receiving TYMLOS and 0.5% of patients receiving placebo.

Dizziness was reported by more TYMLOS-treated patients (10%) compared to placebo (6%) . Tachycardia In women with postmenopausal osteoporosis, adverse reactions of tachycardia, including sinus tachycardia, were reported in 2% of patients receiving TYMLOS and 1% of patients in the placebo group. In 5 of the 13 patients receiving TYMLOS who experienced tachycardia, symptoms occurred within 1 hour of administration. TYMLOS has been associated with a dose-dependent increase in heart rate which developed within 15 minutes after injection and resolved in about 6 hours . Injection Site Reactions During the first month of the trial, injection site reactions were assessed daily one-hour after injection.

TYMLOS had a higher incidence than placebo of injection site redness (58% vs. 28%), edema (11% vs. 3%), and pain (10% vs. 7%). Severe redness, severe edema, and severe pain were reported among 2.9%, 0.4%, and 0.4% of the TYMLOS-treated patients. Laboratory Abnormalities Hypercalcemia In the clinical trial of women with postmenopausal osteoporosis, TYMLOS caused increases in serum calcium concentrations . The incidence of hypercalcemia, defined as albumin-corrected serum calcium ≥10.7 mg/dL at 4 hours following injection at any visit, was 3% in TYMLOS-treated patients and 0.1% with placebo.

Pre-dose serum calcium was similar to baseline in both groups. There were 2 (0.2%) TYMLOS-treated patients and no placebo-treated patients who discontinued from the study due to hypercalcemia. The incidence of hypercalcemia with TYMLOS was higher in patients with mild or moderate renal impairment (4%) compared to patients with normal renal function (1%).

Increases in Serum Uric Acid TYMLOS increased serum uric acid concentrations. In the postmenopausal osteoporosis trial, among patients with normal baseline uric acid concentrations, 25% of patients in the TYMLOS group and 6% of patients in the placebo group had at least one post-baseline concentration above the normal range. The hyperuricemia observed in TYMLOS-treated patients was not associated with an increase in adverse reactions of gout or arthralgia over that observed with placebo.

Hypercalciuria and Urolithiasis In the clinical trial of women with postmenopausal osteoporosis, the overall incidence of urine calcium:creatinine ratio >400 mg/g was higher with TYMLOS than with placebo (20% vs 15%, respectively). Urolithiases were reported in 2.1% of TYMLOS-treated patients and 1.7% of placebo-treated patients. Adverse Reactions from the Extension Study in Postmenopausal Women with Osteoporosis Following 18 months of treatment with TYMLOS or placebo, 1139 women transitioned to treatment with alendronate 70 mg administered orally once weekly.

The incidence of adverse events occurring during alendronate treatment was similar in patients with prior placebo or TYMLOS therapy . Adverse Reactions from Clinical Trial in Men with Osteoporosis The safety of TYMLOS was evaluated in a randomized, multicenter, double-blind, placebo-controlled clinical trial in men with osteoporosis aged 42 to 85 years (mean age 68 years) who were randomized to receive 80 mcg of TYMLOS (N = 149) or placebo (N = 79), given subcutaneously once daily for 12 months . In this study, no patient from either treatment group had an adverse reaction with a fatal outcome during the trial. Serious adverse reactions were reported by 5.4% of subjects treated with TYMLOS and 5.1% of subjects in the placebo group. Adverse reactions leading to study drug discontinuation were reported for 6.7% of patients treated with TYMLOS and 5.1% of patients receiving placebo.

The most common adverse reaction leading to study drug discontinuation in the TYMLOS group was dizziness (2%). Table 2 shows the most common adverse reactions in the trial. These adverse reactions were generally not present at baseline, occurred more commonly with TYMLOS than with placebo and occurred in at least 2% of the patients treated with TYMLOS. Table 2: Common Adverse Reactions Reported in Men with Osteoporosis Adverse reactions reported in ≥2% of TYMLOS-treated patients.

Adverse reactions of orthostatic hypotension were reported in 1% of patients receiving TYMLOS and 0 patients receiving placebo. Dizziness was reported by more TYMLOS-treated patients (9%) compared to placebo (1%) . Laboratory Abnormalities Hypercalcemia In the clinical trial of men with osteoporosis, TYMLOS caused increases in serum calcium concentrations . The incidence of hypercalcemia, defined as albumin-corrected serum calcium ≥10.8 mg/dL at 4 hours following injection at any visit, was 3% in TYMLOS-treated patients and 0% with placebo.

Pre-dose serum calcium was similar to baseline in both groups. The incidence of hypercalcemia, defined as albumin-corrected serum calcium ≥10.8 mg/dL at 4 hours following injection, with TYMLOS was higher in patients with mild or moderate renal impairment (4%) compared to patients with normal renal function (0%). Increases in Serum Uric Acid TYMLOS increased serum uric acid concentrations.

In the male osteoporosis trial, among patients with normal baseline uric acid concentrations, 7% of patients in the TYMLOS group and 6% of patients in the placebo group had at least one post-baseline concentration above the normal range. The hyperuricemia observed in TYMLOS-treated patients was not associated with an increase in adverse reactions of gout or arthralgia over that observed with placebo. Hypercalciuria and Urolithiasis In the clinical trial of men with osteoporosis, the overall incidence of urine calcium: creatinine ratio >400 mg/g was not greater with TYMLOS than with placebo.

Urolithiases were reported in 2% of TYMLOS-treated patients and 1% of placebo-treated patients.

6.2Postmarketing Experience The

following adverse reactions have been identified during the post-approval use of TYMLOS. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Abdominal distension, abdominal pain, abdominal discomfort Constipation, diarrhea, vomiting, decreased appetite Asthenia, lethargy, malaise, feeling abnormal, hot flush Insomnia Hypersensitivity and anaphylactic reactions, dyspnea (in the context of allergic reactions) Pruritus, rash Generalized pain and pain in bone, joint, back, and extremity Blood pressure increased Muscle spasms of the leg and back Injection site reactions including bruising, hemorrhage, pruritus, and rash
